[go-nuts] [ANN] Gop - Build and manage your Go applications out of GOPATH

GOP is a project manangement tool for building your golang applications out of GOPATH. Also this means it's not go-getable. GOP copy all denpendencies to src/vendor directory and all application's source is also in this directory. A normal process using gop is below: git clone

Re: [go-nuts] Go 2 suggestion - what dependencies included in a build?

Keep in mind that you can't assume vcs info is available at build time. They may be building from a downloaded tarball, in which case you *may* have a Gopkg.lock (if everyone uses dep) but not much else. They may be Debian and build from source packages where the Go compiler sees no version

[go-nuts] Re: memmove receives NULL src and positive length?

Just a minor correction: go tool objdump showed that *golang does not touch the pointer value before overwriting it*. The situation does occur nevertheless because obj.data may be nil [0x0,0,0] initially, and length/capacity are assigned before the data pointer is set: obj.data : [0x0,0,0]

[go-nuts] Re: append() gotcha!

Wrote it up as an issue: https://github.com/golang/go/issues/21482 and I agree that using append to assign to a different variable than the one in the append call is almost always going cause surprising behavior but it's less clearly a mistake than append with only a single argument. On

Hello, I was wondering if I should assume BSD 3 clause licenses for all the files located under x/image/testdata and x/image/font/testdata since there are no licese notes regarding those files (fonts and images). Thanks for the input and I am sorry if this is not the right place for this

Re: [go-nuts] Go 2 suggestion - what dependencies included in a build?

I note it as something for Go 2, if only because it would be good to standardize it across all Go binaries, so it was possible to introspect *every* Go executable. Otherwise, I have to push to get all teams using go to adopt the same approach to building in this information, rather than having

[go-nuts] Re: studying golang code

One of the things I love about Go is that the standard library is very readable, even for beginners (relative to the standard libraries of other languages). I think the database/sql package is great. The way it uses interfaces to handle testing is a good example of good quality code IMO. On

Hi, Have you tried the golang.org/x/mobile/example/network example? It's a "pure" Go app that doesn't use Java bindings, but its network access properties should be the same. If that works, you could modify golang.org/x/mobile/example/bind to introduce a simple http.Get (or net.Dial) and see

Re: [go-nuts] defer func() { _ = resp.Body.Close() }()

As far as I'm concerned, `defer resp.Body.Close()` is perfectly cromulent and there's no need to for error checking contortions to satisfy the lint tool. If we're talking about a http.Request I doubt that the close can ever fail (I haven't checked; but it doesn't seem like something that would

[go-nuts] Re: append() gotcha!

Agreed, append with only one argument doesn't look good and should be vetted. As a superset of this problem, any use of *a* = append(*b*, *c*) with *b* != *a* (i.e. not assigning back to the same slice variable) looks either broken or cryptic me. This holds whether *c* is zero or one or more

[go-nuts] defer func() { _ = resp.Body.Close() }()

To pass errcheck I need to do something like defer func() { _ = resp.Body.Close() }() instead of defer resp.Body.Close() Is this something the errcheck tool can figure out to mark as valid instead or does the errcheck tool need help from the compiler so the second case is also ok? -- You

Do you mean ordered map or sorted map... either way, as long as the N is small, then you can use a slice to provide the extra functionality: 1. sorted map https://play.golang.org/p/oLM4u5HwQ6 2. ordered map https://play.golang.org/p/OFXhFyyrmZ On Wednesday, 16 August 2017 03:17:29 UTC+3, Tong

Re: [go-nuts] XML newline escaping

That makes sense, and in fact my XML output with s gets parsed later correctly. My personal use case has input XML files with literal LF characters, and it's frustrating that when my Go program modifies that file, they're all converted, which makes my git commit including that XML file messy.
